In supermarkets and open-concept convenience stores, modular island display cases and air curtain display cases are two indispensable types of core refrigeration equipment. Island cabinets are typically placed in the center aisle of supermarkets to allow customers to access products from both sides. When combined and linked together, they form a continuous, high-capacity display area, primarily used for storing frozen meats, dumplings, tangyuan, or ice cream.

When selecting commercial food preparation equipment (such as sink stations, prep tables, and cutting stations), the numbers “304” and “430” may seem to differ by only one digit, but in terms of corrosion resistance and service life, the gap between the two is like night and day.

Commercial beer display cases on the market primarily use two types of cooling systems: direct cooling and air cooling. The choice between the two directly determines the temperature performance inside the cabinet, the amount of maintenance required, and the unit’s long-term energy consumption.
